Respond here to let me know you're in, and what army you'll be using. I'll have the map ready, we'll roll to determine the order of picking initial locations, chosing events and making challenges for the first turn. The first turn's battles will be Planetstrike, so bring an Attacker and a Defender list at 2000 pts and at 3000 pts (that's 4 lists) to face all comers (since you won't know until that day who you're facing). If you can't make 3K, just bring 2K lists. If you end up being the Challenged player and you want to go lower than 2K, just trim down the 2K list.
If you really want to be in, but can't make Saturday because you have the duty or something similar, I or someone of your choice will proxy the setup for you.
